Best settings and limits
Best first try
Use Balanced and 720p first. Use stronger compression when size matters more than sharpness.
When this may fail
The browser still needs memory and CPU. Very large videos may be better handled on a desktop browser.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
